Abstract: A photolithographically patterned spring contact is formed on a substrate and electrically connects contact pads on two devices. The spring contact also compensates for thermal and mechanical variations and other environmental factors. An inherent stress gradient in the spring contact causes a free portion of the spring contact to bend up and away from the substrate. An anchor portion remains fixed to the substrate and is electrically connected to a first contact pad on the substrate. The spring contact is made of an elastic material and the free portion compliantly contacts a second contact pad, thereby electrically interconnecting the two contact pads.

Abstract: The printer accepts the print request sent through the network and temporarily stores the image information to be printed in the image signal storage unit and the corresponding setting information into the setting information storage unit. The print request value calculation unit calculates the print request value on the basis of the setting information stored in the setting information storage unit. The printing operation boundary value is set through the manager interface and held in the printing operation boundary value holding unit. The print request value calculated by the print request value calculation unit is compared with the printing operation boundary value at the comparison unit. When the print request value exceeds the printing operation boundary value, the comparison unit delivers the print start signal to the image output unit to thereby continuously print image information corresponding to the print requests having been stored.
